This paper presents a simple PWM technique of capacitor voltage balance for three-level inverters. For the presented PWM technique only DC-link voltage sensor is required. As compared to previous methods, current sensor is not required for the presented technique. Moreover, number of sectors per sextant is divided into six sectors rather than four. The

The Neutral point clamped (NPC) inverter has unbalancing problems of neutral point voltage and DC link capacitors voltages, generally dc link capacitor voltage unbalance leads to neutral point voltage unbalance. In this paper neutral point voltage is balanced using sine PWM associated with phase shift technique.

Predictive current control and DC-link capacitor voltages balancing for four-leg NPC inverters
2013 IEEE International Symposium on Industrial Electronics, 2013This paper presents a finite control set model predictive strategy to control the three-phase four-leg neutral-point-clamped (NPC) inverters. The four-leg NPC inverter delivers power to the unbalanced/nonlinear three-phase loads, and it can produce three output currents independently. The proposed method uses the discrete-time model of the inverter and

Cascaded Multilevel Converter based DSTATCOM using p-q theory with DC link voltage balancing
2011 International Conference on Power and Energy Systems, 2011This paper presents the p-q theory based DSTATCOM for reactive power management to control the power factor in a distribution system which serves resistance-reactance loads. Power factor which is one of the measures of power quality in a distribution system plays an important role in the optimal operation of the power system.
